Part III Administrative Complaint

Case Summary

The Commission filed a complaint with an administrative law judge charging that between 1991 and 1996 Rambus, Inc. joined and participated in the JEDEC Solid State Technology Association (JEDEC), the leading standard-setting industry for computer memory. According to the complaint, JEDEC rules require members to disclose the existence of all patents and patent applications that relate to JEDEC’s standard-setting work. While a member of JEDEC, Rambus observed standard-setting work involving technologies which Rambus believed were or could be covered by its patent applications, but failed to disclose this to JEDEC. In 1999 and 2000, after JEDEC had adopted industry-wide standards incorporating the technologies at issue and the industry had become locked in to the use of those technologies, Rambus sought to enforce its patents against companies producing JEDEC-compliant memory, and in fact has collected substantial royalties from several producers of DRAM (dynamic random access memory). (February 17, 2004)

The administrative law judge dismissed all charges against Rambus, ruling that Commission staff had failed to sustain their burden of proof with respect to all three violations alleged in the complaint. The Initial Decision found that Rambus’ conduct before the JEDEC standard-setting organization did not amount to deception and did not violate any extrinsic duties, such as a duty of good faith to disclose patents or patent applications. The Initial Decision also found that the there was insufficient evidence that there were viable alternatives to Rambus’ technology before the standard setting organization. (August 2, 2006)

The FTC issued an opinion by Commissioner Pamela Jones Harbour concluding that Rambus unlawfully monopolized markets for four computer memory technologies that have been incorporated into industry standards DRAM chips. Drams are widely used in personal computers, servers, printers, and cameras. The Commission found that, through a course of deceptive conduct, Rambus was able to distort a critical standard-setting process and engage in an anticompetitive “hold up” of the computer memory industry. The Commission held that Rambus’s acts of deception constituted exclusionary conduct under 21 Section 2 of the Sherman Act and contributed significantly to Rambus’s acquisition of monopoly power in the four relevant markets.

Chairman Majoras issued the opinion of the Commission on remedy in the Rambus matter. In this opinion, the Commission prescribed a set of remedies barring Rambus from making misrepresentations or omissions to standard-setting organizations, requiring Rambus to license its SDRAM and DDR SDRAM technology and setting limits to the royalty rates it can collect under the licensing agreements including with those firms that may have already incorporated its DRAM technology, and requiring Rambus to employ a Commission-approved compliance officer to ensure it discloses relevant patent information to any standard-setting organizations in which it participates. (April 4, 2007)

Rambus appealed the Commission’s order to the U.S. Court of Appeals for the District of Columbia Circuit, which heard oral arguments in February 2008. In April of 2008, the Court issued an opinion that set aside the Commissions final orders and remanded for further proceedings consistent with the Court's opinion. On February 23, 2009, the Supreme Court denied the Commission's Petition for Writ of Certiorari. On May 14, 2009 the Commission formally dismissed the complaint in the Rambus matter.
